I will argue that this lack of proper definitions is the main reason why
the field of research in Artificial Intelligence (and some of its
subfields like Cognitive Robotics, e.g.) has been
derailed for the last 60 years. <...> There are more than 130
definitions of Data - Information - Knowledge notions. There are more
than 75 definitions of Intelligence.

This lack of agreement on what we're all trying to build is something
I and others have complained about numerous times over the years. Diamant
tries to push things forward with some new definitions that include
ideas from Solomonoff, Kolmogorov, and Chaitin dating back to the 1960s.
He goes on to show a possible interrelation of physical and semantic
information and concludes that semantic information is a mutual
agreement between members of a group and cannot be accessible outside of
that group. Rather than thinking of robotics as a data-processing
computational task, we should be thinking along the lines of
incorporating robots into our group of shared semantic information. For
more, check out Diamant's other
papers on Vision, AI, and robotics.
